Diving Information and Equipment

In 1943, Jacques Cousteau and Emile Gagnon
revolutionized the world of diving with the
invention of the Aqualung, or Self-Contained-Underwater-Breathing-Apparatus
(SCUBA). Since then, scuba diving has become
one of the main ways of performing underwater research. Divers
descend to various depths in order to observe and gather information
about the underwater environment, from minerals, and plant life, to
animal species and environmental impacts. There are many forms of diving,
including cave diving, wreck diving, and deep-sea
diving. Many also dive for recreational purposes. Thanks to the innovation
and availability of modern diving technology, anyone can have the chance
to explore the underwater world.

For all its appeal, diving can be a
very dangerous activity. Besides the immediate concerns of air,
pressure, and temperature, keep in mind that during a dive,
you may carry up to 75 lbs. of equipment into
the water with you. You must have absolute control of all equipment
in order to ensure safety. Concerns regarding sports equipment
in terms of diving include breathing, buoyancy,
visibility, and temperature control.
